To all, whom it may conaem:

Be it known that I, .l-l'nmmczi' t-i'rii'im i, :1 Subject of the Emperor of Gernumy, l'l?l-ltling at Witien-on-theRuhr, (lei-trinity. have invented new and useful l mproveuwnts iu Tubeliolling li illsr, of which the following: is a specifimtion.

This invention relates to tithe rolling, mills.

'iulveu-olling mills haw already been sug gestecl wherein the itillOS are st: ippetl from the nnmclreis and from the supporting rolls of saitl mnncli'els by means of u sti'uiping device, which is pushed forward through the medium of the llll 0S themselves as the llllltl' are rolled on to mitt nuimlrels: :u'ul Wltltll sinniltuneously I'tllSm; weight. the 'tuhea hi ing zil'tei'n'iit'ti sti'ipgied from lllt'! mandrel. and liltl'lldl'tli-l0(.ifi; loy suit! weight when the rolls are moved apart on vompletion of the rolling gums; ol Stltit'l tubes.

in 'the ills of this kind heretofore 511;; gesteil, n nnniher ol tubes have been stripped from their tl'lutlt'li'QlH hy means of :1 eonunon stripper unit weight 'lhi. ltllzillfuftilllkilll' has the tlistulvenlzige that when only one or two of the passes of the rolls illt being: usetl :mtl thin tubes are being rolled the three whieh would he required for stripping 5, ti or more tubes train their i'x'uuuh'els in upplietl to one or two onlj untl thus the tithes are liuhle to he crushed or flu l.

According to line pm nt invention :1 Hut) :ua'te stripper mul.

a are tho girnovetl rollers, the nuuulrel rods and 0 an :ihnttnent for mmportingg; mill rods.

The stripper-tubes L370 are guided to move evenly on the 'L'Oflti b, I: hy llltllllL-i of guide-rollers Z suitably journu'otl them-in :uul running on :-.:1i il mils.

The gtlitll -ltillt'L'S o are arranged in 1!. similar lilaitll'ltt' an it fill-t lt; '1' supportml in any suit"- :thle u'umne us for example on upper beams.

The operation of my improved mill is as follows:-----Vheu tithes 5 r are introtliu-etl into tho fJziHStEl-h ouch tuhe g ulntls against, niul pushes in trout? of it" it :eliippent uhe l1, so its to lil't the (oiiosqmniling \i'eight i.

A: By this means, it is possihlo thut only so umny weights are ltllhltl us are required for the tlnnving-haek of the t't]ll'tfiptltilllllgf nuiuheiot' simultaneously l'callttl tuhwx y. Thus it' only one tube is with-ill this tuho (luring its passage through the rolls only litts its own driving \Vt'l fflll uiul m on.
